Specification of Letters Patent.

Patented July 16, 1906.

Application filed March 1, 1905- Scrial No. 247,910-

.To all whom it may concern.-

Be it known that I, ABEL H. HOGEN, a citizen of the United States, and a resident of Geddes, in the county of Charles Mix and State of South Dakota, have invented a new and Improved Type-Writer, of which the following is a full, clear, and exact description.

My invention relates to improvementsin type-writing machines, the'principal object being to reduce the cost by increasing the simplicity thereof.

An important object of the invention is to do away with the keyboard now ordinarily used on typewriters and the delicate connections with which it is usually provided.

My invention comprises means for accomphshing all of the results obtainable on high-priced machines of a complicated nature, these resultsbeing obtained by means which render it possible to build a machine that will have very few delicate and easily broken or deranged parts and atthe same timewill be capable of being built at a low cost.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a type-writing machine built in accordance with the principle of my invention, parts being shown in section. Fig. 2 is a plan view of the same.

Fig. 3 is an end elevation with parts in section. Fi 4 is a diagrammatic rear view of a portion the machine, Fig. 5 is a perspective view of a detail; and Fig. 6 is asectional view, on an enlarged scale, of the device shown in Fig. 5.

" trac guided by these ways.

The machine comprises a base 10, on which are supported a pair of toothed tracks 11. These tracks are provided with ways 12 on then inner surfaces for the reception of projections 13 on a carriage 14. The carriage is desi ned to travel back and forth along the rise of movin the carriage in one direction T secure flexible connections 15 in the form of a rope; chain, or cable to the front portion of the'carria e and carry them to a Windlass or drum, pre ierably located at the front portion of the machine. Thiswindlass is-mounted upon a shaft 16, provided with a ratchetwheel 17, and the latter is designed to be operated by a lever 18, having a pawl 19 pivotally mounted thereon and designed to engage in the teeth of the ratchet-wheel.- The pawl For the pur-.

is provided with a pair of springs 20 and 21, the former for keepin the pawl normally in contact for engaging t e teeth and the latter for returning the lever to its normal position after it has beenswung upon the shaft 16 as a pivot to rotate the ratchet-wheel and drum. A bar 20 is so located as to engage the pawl when the lever is brought to its extreme position and disengage it from the teeth, so that it can be returned.

The lever is. provided with a guide 22, secured to the frame of the machine and having a slot 23 for receiving the lever. The shaft is provided with a resilient brake 24 to hold it in any position in which it may be placed by the pawl. The carria e is normally urged in the opposite direction y means of a spring 25, connected with the rear of the carria e and the rear of the base. It will be readi y understood that the spring will normally hold the carriage in a position as far to the rear as possible and that the operation of the lever 18 will move the carriage forward by a step-by-step motion, it being yieldingly held in any position in which it may be placed by means of the springs 24 and 25.

In order to insure the step-by-step motion of the carriage and provide for an accurate spacin the carriage is provided with a pair of paw s 26, pivoted to the body of the carriage and adapted to engage the teeth 27 of the tracks 11. These pawls are normally held in contact with the teeth by springs 28 and will slide from one tooth to another in such a manner that a backward motion of the carriage would not be possible. The two pawls are rigidly connected together by a shaft 29. In order to provide for throwing these pawls out of operative position when the carriage reaches the end of its stroke, so that it can be drawn back to the rear of the machine by the spring 25, a stud 30 is provided in one of the tracks. This stud will engage one of the pawls, as indicated in Fig. 4, and throw both of them from the position shown in dotted li'nesto that shown. in full lines in an obvious manner, the flexion of the spring '28 normally holding the pawls in the position in which theyare forced by the stud.

When the carriage reaches the otherend of its stroke, one of the pawls 26 comes into contact with an inclined projection 31, which forces it, together with the opposite pawl, back in position for en agin the teeth '27. It should be noticed t at t e end of the spring 28 is held by a rigid clamp 82, which be readi pivoted to the carriage by means of a shaft 34 or the like, this shaft being preferablylocated' at-the front end of the carriage and of the frame and being mounted in slots 35 in the frame, so that it can be readily removed.

The frame is provided with a shaft 36, on which is mounted a type-wheel 37. This typ'e-wheel'is provided upon its edge with a succession of characters 38, which may be of any desiredkind. It is also' provided with characters 39 upon its side in order that the particular character which is located atv the bottom, and therefore in position for printing, may .be designated by a pointer 40, lo-

cated'near the bottom of the carriage.

In order-to rotate the type-wheel to the roper position-for resenting the re uired etter at the bottom or printing, a pul ey' 41 is mounted on the shaft 36 and rlgidly con nested with respect to the type-wheel. This is provided with a belt 42, passing over a ul ley 43 on the shaft 34. On the same sha t is mounted another pulley 44, connectedby-a belt 45 with a pulley 46' upon a shaft, 47, mounted onthe frame of the carriage. The shaft 47 is provided with a ratchet-wheel 48, rigidly mounted with res ect to the pulley 46, and a lever 49, pivota y mounted onthe shaft 47, is 'rovided with a pawl 50, engag ing the teet of the ratchet-wheel and yiel ingly held in contact with the teeth by means of a spring 51. A spring 52, connected with the carriage and with the lever, is provided for returnlhg the lever to normal position after it has been manipulated to setthe wheel. A guide 53, provided'with a slot 54, is rovided for the lever.

hen the wheel is set in proper; osition, the printing is accomplished for a letters and all characters by forcing the frame'33 downwardjabout its pivot 34, and this is accomplished by means of a key 55, mounted onarod 56, which is connected with the rear end. of the frame 33 and is provided, with a guide 57, rigidly mounted on the carriage. A spring 58 is connected: with the lower por tion offthe rod 56 for normally returning the rod-and carriage to their most elevated position after being depressed-to print a character. The spring 58 is preferabl' connected with. clamps 59, each pivotaly mounted u on the frame offthe carriage. The bottom 0 the carriage carries a sheet-metal guard.

connected with a] re upon the oppositeside ofthemachlne; This s the machine.

vided for the paper, a glass plate 62 is 10- oated'in the base of the machine between the tracks and throughout the printing length of Y the device.

Many different forms of inking devices may be employedjbut I prefer a frame 63, pivot-ally connected with the shaft 34 and' carrying a ad 64 upon its inner face. At the top of te frame i's'an' ink cu 65,,having a cover 66 and a well'67. Awrck 68 in; the

cup, connects the fresh ink therein with the" interior of the well, which in turn is-connected by a passage 69 with the ad 64, so; that ink will be conducted by ca-pi lary attraction into the well and thence by gravityto the pad. The characters as they pass the pad will be inked in an obvious manner.

pad can be turned down when not in-use.

The means which I have illustrated for holding and feeding the pa er comprises a The roll 7 0, having aslot' 71, an 'a-pivoted-'plate 7 2, adapted to enter-said slot' and clamp the paper in it, as shown in Fig. 6. This rollis mounted-inbe'arings 73 and is provided with a hand-wheel7'4' for operating 1t. Upon the opposite end itii's 'provided with a roll 75-,

adapted to carry a ta e.76,'which in turn is 77 upon a shaft-'78 aft i's alsoprovided with a-hand-wheel 79 and' is mounted in bearings 80" upon the fra'ne of. themachina- Ai pointer 81' is mounted on the machine forindic-ating. on
